More than 100 million pounds of garbage is generated by national park visitors each year. Here's what you can do to help.
A recent survey conducted by Subaru of America and the National Parks Conservation Association found that a majority of Americans (59%) are unaware of the monumental waste challenges facing the country's national parks.
What's more, a second study found that the bulk of that waste is coming from outside the parks and that the lion's share of the garbage is food waste and plastic water bottles.
